More information on products for use in stem cell culture may be found here. Are Sigma cell culture products manufactured to cGMP?
• The cell culture media products that Sigma-Aldrich offer are generally manufactured in a cGMP environment. The biochemicals and other reagents in the catalogue, however, are not manufactured to cGMP. If a cGMP product is required it is possible to order this as a custom item, but this is likely to be more expensive than purchasing a catalogue item.
